Section 1‐05.7 is supplemented as follows:
(******)
Upon written notice from the Engineer, the Contractor shall promptly replace and re‐execute Work by
Contractor forces, in accordance with the intent of the Contract and without expense to the Owner,
and shall bear the expense of making good all Work of other contractors destroyed or damaged by
such removal or replacement.
If the Contractor does not remove such condemned Work and materials and commence re‐execution
of the Work within 7 calendar days of written notice from the Engineer, or fails to perform any part of
the Work required by the Contract Documents, the Owner may correct and remedy such Work as may
be identified in the written notice, with Contracting Agency forces or by such other means as the
Contracting Agency may deem necessary. In that case, the Owner may store removed material.
Direct or indirect costs incurred by the Contracting Agency attributable to correcting and remedying
defective or unauthorized Work, or Work the Contractor failed or refused to perform, shall be paid by
the Contractor. Payment will be deducted by the Engineer from monies due, or to become due, the
Contractor. Such direct and indirect costs shall include in particular, but without limitation,
compensation for additional professional services required, and costs for repair and replacement of
Work of others destroyed or damaged by correction, removal, or replacement of the Contractor’s
unauthorized Work.
If sufficient funds do not remain in the Contract and the Contractor does not pay the cost of such
removal and storage within 10 calendar days from the date of the notice to the Contractor of the fact
of such removal, the Owner may, upon an additional 10 calendar days written notice, sell such
materials at public or private sale, and deduct all costs and expenses incurred from monies due to the
Contractor, including costs of sale, and accounting to Contractor for the net proceeds remaining. The
Owner may bid at any such sale. The Contractor shall be liable to the Owner for the amount of any
deficiency from any funds otherwise due the Contractor.
If the Contractor fails to comply with a written order to remedy what the Engineer determines to be
an emergency situation, the Engineer may have the defective and unauthorized Work corrected
immediately, have the rejected Work removed and replaced, or have Work the Contractor refuses
to perform completed by using Contracting Agency or other forces. An emergency situation is any
situation when, in the opinion of the Engineer, a delay in its remedy could be potentially unsafe, or
might cause serious risk of loss or damage to the public, the Property Owner and the Property
Owner’s property.
No adjustment in contract time or compensation will be allowed because of the delay in the
performance of the Work attributable to the exercise of the Contracting Agency’s rights provided by
this section.
The rights exercised under the provisions of this section shall not diminish the Contracting Agency’s
right to pursue any other avenue for additional remedy or damages with respect to the Contractor’s
09/11/2018
25
failure to perform the Work as required.
1‐05.10 Guarantees
Section 1‐05.10 is supplemented as follows:
(******)
If within one year after the Acceptance Date of the Work by the Contracting Agency, defective and/or
unauthorized Work is discovered, the Contractor shall promptly, upon written order by the Contracting
Agency, return and in accordance with the Engineer’s instructions, either correct such Work, or if such
Work has been rejected by the Engineer, remove it from the project site and replace it with non‐
defective and authorized Work, all without cost to the Contracting Agency. If the Contractor does not
promptly comply with the written order to correct defective and/or unauthorized Work, or if an
emergency exists, the Contracting Agency reserves the right to have defective and/or unauthorized
Work corrected or removed and replaced pursuant to Section 1‐05.7 “Removal of Defective and/or
Unauthorized Work.”
The Contractor agrees the above one year limitation shall not exclude or diminish the Contracting
Agency’s rights under any law to obtain damages and recover costs resulting from defective and/or
unauthorized Work discovered after one year but prior to the expiration of the legal time period set
forth in RCW 4.16.040 limiting actions upon a contract in writing, or liability expressed of implied
arising out of a written agreement.
The Contractor shall warrant good title to all materials, supplies, and equipment purchased for, or
incorporated in the Work. Nothing contained in this paragraph, however, shall defeat or impair the
right of persons furnishing materials or labor, to recover under any bond given by the Contractor for
their protection, or any rights under any law permitting such persons to look to funds due the
Contractor in the hands of the Contracting Agency.
The provisions of this paragraph shall be inserted in all subcontracts and material contracts, and notice
of its provisions shall be given to all persons furnishing materials for the Work when no formal contract
is entered into for such materials.
1‐05.11 Final Inspection
1‐05.11(1) Substantial Completion Date
Section 1‐05.11(1) is a new section:
(******)
When the Contractor considers the Work to be substantially complete, the Contractor shall so notify
the Engineer and request the Engineer establish the Substantial Completion Date. The Engineer will
schedule an inspection of the Work with the Contractor to determine the status of completion.
To be considered substantially complete the following conditions must be met:
1. The Contracting Agency must have full and unrestricted use and benefit of the
facilities both from the operational and safety standpoint.
2. Only minor incidental Work, replacement of temporary substitute facilities, or
correction of repair Work remains to reach physical completion of the Work.
The Contractor’s request shall list the specific items of Work in subparagraph two above that
remains to be completed in order to reach physical completion. The Engineer may also establish the
Substantial Completion Date unilaterally.
If after this inspection, the Engineer concurs with the Contractor that the Work is substantially
complete and ready for its intended use, the Engineer, by written notice to the Contractor, will set
the Substantial Completion Date. If, after this inspection the Engineer does not consider the Work
substantially complete and ready for its intended use, the Engineer will, by written notice, so notify
the Contractor giving the reasons therefore.
Upon receipt of written notice concurring in or denying substantial completion, whichever is
09/11/2018
26
applicable, the Contractor shall pursue vigorously, diligently and without unauthorized interruption,
the Work necessary to reach Substantial and Physical Completion. The Contractor shall provide the
Engineer with a revised schedule indicating when the Contractor expects to reach substantial and
physical completion of the Work.
The above process shall be repeated until the Engineer establishes the Substantial Completion Date
and the Contractor considers the Work physically complete and ready for Final Inspection.
1‐05.11(2) Final Inspection and Physical Completion Date
Section 1‐05.11(2) is a new Section:
(******)
When the Contractor considers the Work physically complete and ready for Final Inspection, the
Contractor, by Written Notice, shall request the Engineer to schedule a final inspection. The Engineer
will set a date for Final Inspection. The Engineer and the Contractor will then make a final inspection
and the Engineer will notify the Contractor in writing of all particulars in which the Final Inspection
reveals the Work incomplete or unacceptable. The Contractor shall immediately take such corrective
measures as are necessary to remedy the listed deficiencies. Corrective Work shall be pursued
vigorously, diligently, and without interruption until physical completion of the listed deficiencies. This
process will continue until the Engineer is satisfied the listed deficiencies have been corrected.
If action to correct the listed deficiencies is not initiated within 7 days after receipt of the Written
Notice listing the deficiencies, the Engineer may, upon Written Notice to the Contractor, take
whatever steps are necessary to correct those deficiencies pursuant to Section 1‐05.8. The
Contractor will not be allowed an extension of contract time because of a delay in the performance
of the Work attributable to the exercise of the Engineer’s right hereunder.
Upon correction of all deficiencies, the Engineer will notify the Contractor and the Contracting Agency,
in writing, of the date upon which the Work was considered physically complete, that date shall
constitute the Physical Completion Date of the Contract, but shall not imply all the obligations of the
Contractor under the Contract have been fulfilled.
1‐05.11(3) Operational Testing
Section 1‐05.11(3) is a new section:
(******)
Unless otherwise noted in the Contract Documents, the Contractor shall give the Engineer a minimum
of 3 working days’ notice of the time for each test and inspection. If the inspection is by another
authority than the Engineer, the Contractor shall give the Engineer a minimum of 3 working days’
notice of the date fixed for such inspection. Required certificates of inspection by other authority than
the Engineer shall be secured by the Contractor.
It is the intent of the Contracting Agency to have at the Physical Completion Date a complete and
operable system. Therefore, when the Work involves the installation of machinery or other
mechanical equipment; street lighting, electrical distribution or signal systems; irrigation systems;
buildings; or other similar Work, it may be desirable for the Engineer to have the Contractor operate
and test the Work for a period of time, after final inspection but prior to the physical completion
date. Whenever items of Work are listed in the Contract Provisions for operational testing they shall
be fully tested under operating conditions for the time period specified to ensure their acceptability
prior to the Physical Completion Date. During and following the test period, the Contractor shall
correct any items of workmanship, materials, or equipment which prove faulty, or that are not in
first class operating condition. Equipment, electrical controls, meters, or other devices and
equipment to be tested during this period shall be tested under the observation of the Engineer, so
that the Engineer may determine their suitability for the purpose for which they were installed. The
Physical Completion Date cannot be established until testing and corrections have been completed
to the satisfaction of the Engineer.
09/11/2018
27
The costs for power, gas, labor, material, supplies, and everything else needed to successfully
complete operational testing, shall be included in the unit contract prices related to the system
being tested, unless specifically set forth otherwise in the proposal.

1‐07.2 State Sales Tax
Delete this section, including its sub‐sections, in its entirety and replace it with the following:
(******)
1‐07.2(1) General
The Washington State Department of Revenue has issued special rules on the state sales tax.
Sections 1‐07.2(1) through 1‐07.2(4) are meant to clarify those rules. The Contractor should contact
the Washington State Department of Revenue for answers to questions in this area. The
Contracting Agency will not adjust its payment if the Contractor bases a bid on a misunderstood tax
liability.
The Contractor shall include all Contractor‐paid taxes in the unit bid prices or other contract
amounts. In some cases, however, state retail sales tax will not be included. Section 1‐07.2(3)
describes this exception.
The Contracting Agency will pay the retained percentage only if the Contractor has obtained from
the Washington State Department of Revenue a certificate showing that all contract‐related taxes
have been paid (RCW 60.28.050). The Contracting Agency may deduct from its payments to the
Contractor any amount the Contractor may owe the Washington State Department of Revenue,

the proper state fund
1‐07.2(2) State Sales Tax – Rule 171
WAC 458‐20‐171, and its related rules, apply to building, repairing, or improving streets, roads, etc.,
which are owned by a municipal corporation, or political subdivision of the state, or by the United
States, and which are used primarily for foot or vehicular traffic. This includes storm or combined
sewer systems within and included as part of the street or road drainage system, and power lines
when such are part of the roadway lighting system. For Work performed in such cases, the
Contractor shall include Washington State Retail Sales Taxes in the various unit bid item prices, or
other contract amounts, including those that the Contractor pays on the purchase of the materials,
equipment, or supplies used or consumed in doing the Work.
1‐07.2(2) State Sales Tax – Rule 170
09/11/2018
31
WAC 458‐20‐170, and its related rules, applies to the constructing and repairing of new or existing
buildings, or other structures, upon real property. This includes, but is not limited to; the
construction of streets, roads, highways, etc., owned by the state of Washington; water mains and
their appurtenances; sanitary sewers and sewage disposal systems unless such sewers and disposal
systems are within, and a part of, a street or road drainage system; telephone, telegraph, electrical
power distribution lines, or other conduits or lines in or above streets or roads, unless such power
lines become a part of a street or road lighting system; and installing or attaching of any article of
tangible personal property in or to real property, whether or not such personal property becomes a
part of the realty by virtue of installation.
For Work performed in such cases, the Contractor shall collect from the Contracting Agency, retail
sales tax on the full contract price. The Contracting Agency will automatically add this sales tax to
each payment to the Contractor. For this reason, the Contractor shall not include the retail sales tax
in the unit bid item prices, or in any other contract amount subject to Rule 170, with the following
exception.
Exception: The Contracting Agency will not add in sales tax for a payment the Contractor or a

of entry, at no additional cost to the Owner. The Contractor is required to indemnify the Owner
from claims on all easements and rights of entry.
All other permits, licenses, etc., shall be the responsibility of the Contractor. The Contractor shall
comply with the special provisions and requirements of each.
Permits, permission under franchises, licenses and bonds of a temporary nature necessary for and
during the prosecution of the Work, and inspection fees in connection therewith shall be secured
and paid for by the Contractor. If the Owner is required to secure such permits, permission under
09/11/2018
32
franchises, licenses and bonds, and pay the fees, the costs incurred by the Owner thereby shall be
charged against the Contractor and deducted from any funds otherwise due the Contractor.
The Contractor is cautioned to review all permits and other Contract Documents and schedule the
work activities appropriately to complete the work within the number of days stated in the Contract
Document. No additional compensation or extensions to time will be granted to the Contractor due
to the time constraints imposed by such documents. The Contractor shall assume all responsibility
for meeting all requirements of all permits.
Any fines or penalties incurred by Contracting Agency for not meeting state water quality standards
and/or lack of stormwater pollution prevention on this Project shall be deducted from monies

09/11/2018
34
The Contractor shall also prepare a final SWPPP. The SWPPP must meet the requirements of the
Department of Ecology’s NPDES and State Waste Discharge General Permit for Stormwater
Discharges Associated With Construction Activity (General Permit). The SWPPP shall include and
modify as necessary the Site Preparation and Erosion Control Plan drawings provided as part of the
Contract Plans. The Contractor shall prepare, review, and modify the SWPPP as necessary to be
consistent with the actual work schedule, sequencing, and construction methods that will be used
on the project. The Contractor’s SWPPP shall meet the requirements of the general permit.
The Contractor shall:
Furnish, install, operate, and maintain necessary machinery, appurtenances, and equipment

Dewater and dispose of water in a manner that will not cause injury to public and private
property, as well as keep sediment‐laden water from entering the City surface water system
or violate applicable water standards;
Keep sufficient pumping equipment and machinery on hand at all times for emergencies,
including electric power failures;
Keep experienced personnel available at all times to operate pumping equipment, machinery
and appliances;
Not shut down dewatering systems between shifts, on holidays and weekends, nor during
work stoppages without prior authorization by the Engineer;
Control groundwater to prevent softening of bottoms of excavations, or formation of “quick”
conditions or “boils”;
Design and operate dewatering system that will not remove natural soils;
Keep excavations free of water during excavation, construction of structures, installation of
pipelines, placing of structures, backfill, and placing and curing of concrete; and
Control surface water runoff to prevent entry and collection in excavations.
As construction progresses and unexpected or seasonal conditions dictate, the Contractor shall
anticipate that more water pollution/erosion control measures will be necessary. It shall be the
obligation and responsibility of the Contractor to revise or supplement the pollution/erosion control
measures as may be needed to protect the work, adjacent properties, storm drains, streams, and
other water bodies.
At all times, there must be material on the job site to handle any spills caused by the Contractor,
such as tack, oils, diesel, etc. Materials would include, but not be limited to, oil absorbent pads and
“kitty litter.” The Contractor must supply said materials at his expense and, in the event of a spill, be
responsible for cleanup and disposal of contaminated materials.
In addition, the SWPPP shall outline the procedures to be used to prevent high pH stormwater or
dewatering water from entering surface waters. The plan shall include how the pH of the water will
be maintained between pH 6.5 and pH 8.5 prior to being discharged from the project or entering
surface waters. Prior to beginning any concrete or grinding work, the Contractor shall submit the
plan, for the Engineer’s review and approval.
An Ecology template is available to the Contractor for producing the SWPPP, using project‐ specific
information added by the Contractor. The template and instructions are available at:
http://www.ecy.wa.gov/programs/wq/stormwater/construction.
The Engineer’s review and any resulting approval of the Contractor’s SWPPP and TESCP will be only
regarding conformance with the specification requirement that the Contractor have the plans
prepared by a CPESC or professional Civil Engineer who has expertise in the type of facilities and
09/11/2018
35
that the SWPPP and TESCP include the items specified for such plans. The Contractor shall be solely
responsible for the adequacy of the SWPPP and TESCP and if erosion sediment, and other pollutant
control measures in deviation or addition to those described in the SWPPP become necessary to
minimize erosion and prevent storm water contamination from sediment and other pollutants, the
Contractor shall prepare and submit a revised SWPPPP to the Engineer for review as specified for
the original plan.
The Owner will not be liable to the Contractor for failure to accept all or any portion of an originally
submitted or revised SWPPP, nor for any delays to the Work due to the Contractor’s failure to
submit and implement an acceptable SWPPP.
1‐07.16 Protection and Restoration of Property

1‐07.17 Utilities and Similar Facilities
Section 1‐07.17 is supplemented by adding:
(******)
Existing utilities indicated in the Plans have been plotted from the best information available to the
Engineer. Information and data shown or indicated in the Contract Documents with respect to existing
underground utilities or services at or contiguous to the project site are based on information and
data furnished to the Owner and the Engineer by owners of such underground facilities or others, and
the Owner and the Engineer do not assume responsibility for the accuracy or completeness thereof.
It is to be understood that other aboveground or underground facilities not shown in the Plans may
be encountered during the course of the Work.
All utility valves, manholes, vaults, or pull boxes which are buried shall be conspicuously marked in a
fashion acceptable to the Owner and the Engineer by the Contractor to allow their location to be
determined by the Engineer or utility personnel under adverse conditions, (inclement weather or
darkness).
Where underground main distribution conduits, such as water, gas, sewer, electric power, or
telephone, are shown on the Plans, the Contractor, for the purpose of preparing his bid, shall assume
that every property parcel will be served by a service connection for each type of utility.
The Contractor shall check with the utility companies concerning any possible conflict prior to
commencing excavation in any area. The Contractor shall resolve all crossing and clearance problems
with the utility company concerned. No excavation shall begin until all known facilities, in the vicinity
of the excavation area, have been located and marked.

Call Before You Dig
The 48‐Hour Locators
1‐800‐424‐5555
At least 2 and not more than 10 working days prior to commencing any excavations for utility potholing
or for any other purpose under this Contract, the Contractor shall notify the Underground Utilities
Location Center by telephone of the planned excavation and progress schedule. The Contractor is also
09/11/2018
37
warned that there may be utilities on the project that are not part of the One Call system. They must
be contacted directly by the Contractor for locations.
The Contractor shall make arrangements 48 hours in advance with respective utility owners to have a
representative present when their utility is exposed or modified, if the utility chooses to do so.
Existing utilities for telephone, power, gas, water, and television cable facilities shall be adjusted or
relocated by the appropriate utility company unless otherwise noted in the Plans. These adjustments
may be completed before the Contractor begins Work, or may be performed in conjunction with the
Contract Work. The Contractor shall be entirely responsible for coordination with the utility
companies and arranging for the movement or adjustment, either temporary or permanent, of their
facilities within the project limits. See also Section 1‐05.14 of these Special Provisions.
If or when utility conflicts occur, the Contractor shall continue the construction process on other
aspects of the project whenever possible. No additional compensation will be made to the Contractor
for reason of delay caused by the actions of any utility company, and the Contractor shall consider
such costs to be incidental to the other items of the Contract.
Utility Potholing
Potholing may be included as a bid item for use in determining the location of existing utilities in
advance of the Contractor's operations. If potholing is not included as a bid item then it shall be
considered incidental to other Work. The Contractor shall submit all potholing requests to the
Engineer for approval, at least 2 working days before potholing is scheduled. Additionally, the
Contractor shall provide potholing at the Engineer's request.
In no way shall the Work described under Utility Potholing relieve the Contractor of any of the
responsibilities described in Section 1‐07.17 of the Standard Specifications and Special Provisions, and
elsewhere in the Contract Documents.
1‐07.17(1) Site Specific Potholing
Section 1‐07.17(1) is a new section:
(******)
Site Specific Potholing is intended to be additional potholing as directed by the Engineer, which is in
addition to potholing included as incidental for utility installation. Where underground utilities are
found to be in the way of construction, such condition shall not be deemed to be a changed or
differing site condition, and if necessary, pipe alignment or grade shall be modified. No payment will
be made unless potholing has been performed prior to trench excavation, and witnessed by the
Engineer. Different utilities may be found to occupy a common trench. Any two or more utilities
separated by 3 feet or less shall constitute one locate. Where multiple utilities exist in close proximity,
the Contractor shall be paid for one locate for every 5 feet of exploration trench. The quantity for this
item is included to provide a common proposal for bid purposes. The actual quantity used in
construction may vary from that amount. The unit price will not be adjusted if the actual quantity
used varies by more than 25 percent.
The contractor shall perform for this potholing a minimum of five working days prior to crossing to
allow for potential revisions. The contractor shall not have cause for claim of down‐time or any other
additional costs associated with ‘waiting’ if the owner provides design revisions (related to the
information supplied per this section) within three working days after the contractor provides the
surveyed elevations.
In no way shall the Work described under Site Specific Potholing relieve the Contractor of any of the
responsibilities described in Section 1‐07.17 of the Standard Specifications and Special Provisions, and
elsewhere in the Contract Documents.

1‐07.17(3) Interruption of Services
Section 1‐07.17(3) is a new section:
(******)
Whenever in the course of the construction operation it becomes necessary to cause an outage of
utilities, it shall be the Contractor's responsibility to notify the affected users and the Engineer not less
than 48 hours in advance of such outage. The Contractor shall make reasonable effort to minimize
the duration of outages, and shall estimate the length of time service will be interrupted and so notify
the users. In the case of any utility outage that has exceeded or will exceed four hours, user contact
shall again be made. Temporary service, if needed, will be arranged by the Contractor at no cost to
the Owner.
Overhead lighting outages shall not exceed 24 hours. All cost to the Contractor for providing
temporary overhead lighting to meet above requirements shall be incidental to the various unit and
Lump sum items of the Contract; no separate payment will be made.
1‐07.17(4) Resolution of Utility Conflicts
(******)
Section 1‐07.17(4) is a new section:
In no way shall the work described under Resolution of Utility Conflicts relieve Contractor of any of
the responsibilities described in Section 1‐07.17 of the Standard Specifications and Special
Provisions, and elsewhere in the Contract Documents. If or when utility conflicts occur, Contractor
shall continue the construction process on other aspects of the project whenever possible.
If “Resolution of utility conflicts” is included as a bid item in Section 1‐09.14, it shall be used to
resolve any new identified utility conflicts not otherwise shown on the Contract Drawing or
Specifications that are identified during the course of construction.
1‐07.18 Public Liability and Property Damage Insurance
Section 1‐07.18 is deleted replaced by the following new section and subsections:

exception.
The City reserves the right to approve the security of the insurance coverage provided by the
insurance company(ies), terms, conditions, and the Certificate of Insurance.
Failure of the Contractor to fully comply during the term of the Contract with these requirements
will be considered a material breach of contract and shall be cause for immediate termination of
the contract at the option of the City.
The Contractor shall obtain and maintain the minimum insurance coverage set forth below. By
requiring such minimum insurance, the City of Renton shall not be deemed or construed to have
assessed the risks that may be applicable to the Contractor. The Contractor shall assess its own

The Contractor shall provide one drivable roadway lane and maintain convenient access for local and
commuter traffic to driveways, businesses, and buildings along the line of Work throughout the course
of the project. Such access shall be maintained as near as possible to that which existed prior to the
commencement of construction. This restriction shall not apply to the paving portion of the
construction process.
The Contractor shall notify and coordinate with all property owners and tenants of street closures, or
other restrictions which may interfere with their access at least 24 hours in advance for single‐family
residential property, and at least 48 hours in advance for apartments, offices, and commercial

the Contract by other access, the existing access shall not be closed until the replacement access
facility is available.
All unattended excavations shall be properly barricaded and covered at all times. The Contractor shall
not open any trenches that cannot be completed and refilled that same day. Trenches shall be patched
or covered by a temporary steel plate, at the Contractor’s expense, except in areas where the roadway
remains closed to public traffic. Steel plates must be anchored.
1‐07.23(2) Construction and Maintenance of Detours
(******)
Revise the first paragraph to read:
Unless otherwise approved, the Contractor shall maintain two‐way traffic during construction. The
Contractor shall build, maintain in a safe condition, keep open to traffic, and remove when no longer
needed:
1. Detours and detour bridges that will accommodate traffic diverted from the roadway, bridge,
sidewalk, driveway, or path during construction,
2. Detour crossings of intersecting highway, and
3. Temporary approaches.
1‐07.24 Rights‐of‐Way
Delete this section in its entirety, and replace it with the following:
(******)
Street right‐of‐way lines, limits of easements, and limits of construction permits are indicated on the
Drawings. The Contractor’s construction activities shall be confined within these limits unless
arrangements for use of private property are made.
Generally, the Contracting Agency will have obtained, prior to bid opening, all rights‐of‐way and
easements, both permanent and temporary, necessary for carrying out the completion of the Work.
Exceptions to this are noted in the Contract Documents or brought to the Contractor’s attention by a
duly issued addendum.
Whenever any of the Work is accomplished on or through property other than public right‐of‐way, the
Contractor shall meet and fulfill all covenants and stipulations of any easement agreement obtained
by the Contracting Agency from the owner of the private property. Copies of the easement
agreements are included in the Contract Provisions or made available to the Contractor as soon as
practical after they have been obtained by the Engineer.
Whenever easements or rights‐of‐entry have not been acquired prior to advertising, these areas are
so noted on the Drawings. The Contractor shall not proceed with any portion of the Work in areas
where right‐of‐way, easements, or rights‐of‐entry have not been acquired until the Engineer certifies
to the Contractor that the right‐of‐way or easement is available or that the right‐of‐entry had been
received. If the Contractor is delayed due to acts of omission on the part of the Contracting Agency in
obtaining easements, rights of entry of right‐of‐way, the Contractor will be entitled to an extension of
time. The Contractor agrees that such delay shall not be a breach of contract.
Each property owner shall be given 48 hours notice prior to entry by the Contactor. This includes entry
onto easements and private property where private improvements must be adjusted.
The Contractor shall be responsible for providing, without expense or liability of the Contracting
Agency, any additional land and access thereto that the Contractor may desire for temporary
construction facilities, storage of materials, or other Contractor needs. However, before using any
private property, whether adjoining the Work or not, the Contractor shall file with the Engineer a
09/11/2018
44
written permission of the private property owner, and, upon vacating the premises, a written release
from the property owner of each property disturbed or otherwise interfered with by reasons of
construction pursued under this Contract. The statement shall be signed by the private property
owner, or proper authority acting for the owner of the private property affected, stating that
permission has been granted to use the property and all necessary permits have been obtained or, in
the case of a release, that the restoration of the property has been satisfactorily accomplished. The
statement shall include the parcel number, address and date of signature. Written releases must be
filed with the Engineer before the Completion Date will be established.
1‐07.28 Confined Space Entry
Section 1‐07.28 is new:
The Contractor shall:
1. Review and be familiar with the City’s Public Works Confined Space Entry Program.
2. Review documented information about the City confined spaces in which entry is intended as
listed and described in the City’s Attribute and Map Book. This information includes identified
hazards for each permit‐required confined space.
3. Each contractor shall have their own confined space entry program. Upon request of the City
they will provide a statement confirming they are in compliance with their confined space
entry program including requirements for confined space training for employees associated
with the project in Renton.
4. Be responsible for following all confined space requirements established by the provisions in
WAC 296‐809 and its chapters.
5. Coordinate entry operations with the City of Renton when employees from the contractor will
be working in or near City confined spaces.
6. Discuss entry operations with the City of Renton including the program followed during
confined space entry.
7. Debrief the City on any hazards confronted or created at the completion of entry operations.
8. Place signs stating, “Danger, Follow Confined Space Entry Procedure before Entering” at each
confined space to be entered. Never leave the confined space open and unattended.
The contractor’s or consultant’s point of contact with the City in regard to confined space entry will
be the City’s assigned construction inspector.

Contractor exceeds the Contracting Agency’s noise control regulations or complaints are received from
the public or adjoining property owners regarding the noise from the Contractor’s operations. The
Contractor shall have no claim for damages or delays should such permission be revoked for these
reasons.
Permission to Work Saturdays, Sundays, holidays or other than the agreed upon normal straight time

shifts occur in a single 24‐hour period. Assistants may include, but are not limited to, survey crews;
personnel from the material testing labs; inspectors; and other Contracting Agency employees when
in the opinion of the Engineer such Work necessitates their presence.
1‐08.0(3) Reimbursement for Overtime Work of Contracting Agency Employees
Section 1‐08.0(3) is a new subsection:
(******)
Where the Contractor elects to Work on a Saturday, Sunday, holiday, or longer than an 8‐hour Work
shift on a regular working day, as defined in the Standard Specifications, such Work shall be
considered as overtime Work. On all such overtime Work an inspector will be present, and a survey
crew may be required at the discretion of the Engineer. The Contractor shall reimburse the
Contracting Agency for the full amount of the straight time plus overtime costs for employees and
representative(s) of the Contracting Agency required to work overtime hours.
The Contractor by these Specifications does hereby authorize the Engineer to deduct such costs
from the amount due or to become due the Contractor.
1‐08.1 Subcontracting
Revise the second paragraph to read:
The Contractor shall not subcontract Work unless the Engineer approves in writing. Each request to
subcontract shall be on the form the Engineer provides. If the Engineer requests, the Contractor shall
provide proof that subcontractor has the experience, ability, and equipment the Work requires. The
Contractor shall require each subcontractor to comply with Section 1‐07.9 and to furnish all
certificates and statements required by the Contract. The Contractor shall require each subcontractor
of every tier to meet the responsibility criteria stated in RCW 39.06, and shall include these
requirements in every subcontract of every tier.
Section 1‐08.1 is supplemented as follows:
(******)
Written requests for change in subcontractors shall be submitted by the Contractor to the Engineer at
least 7 calendar days prior to start of a subcontractor's Work.
The Contractor agrees that he/she is fully responsible to the Owner for the acts and omissions of all
subcontractors and lower‐tier subcontractors, and persons either directly or indirectly employed by
the subcontractors, as well as for the acts and omissions of persons directly employed by the
Contractor. The Contractor shall be required to give personal attention to the Work that is sublet.
Nothing contained in the Contract Documents shall create any contractual relation between any
subcontractor and the Owner.
The Contractor shall be responsible for making sure all subcontractors submit all required
09/11/2018
47
documentation, forms, etc.
1‐08.2 Assignment
The second paragraph of Section 1‐08.2 is modified as follows:
(******)
The Contractor shall not assign any moneys due or to become due to the Contractor hereunder
without the prior written consent of the Owner. The assignment, if approved, shall be subject to all
setoffs, withholdings, and deductions required by law and the Contract.
1‐08.3 Progress Schedule
Section 1‐08.3 is supplemented as follows:
(******)
The progress schedule for the entire project shall be submitted 7 calendar days prior to the
Preconstruction Conference. The schedule shall be prepared using the critical path method (CPM),
preferably using Microsoft Project or equivalent software. The schedule shall contain this information,
at a minimum:
1. Construction activities, in sufficient detail that all activities necessary to construct a complete
and functional project are considered. Any activity that has a scheduled duration exceeding
30 calendar days shall be subdivided until no sub‐element has a duration exceeding 30
calendar days.
2. The schedule shall clearly indicate the activities that comprise the critical path. For each
activity not on the critical path, the schedule shall show the float, or slack, time.
3. Procurement of material and equipment.
4. Submittals requiring review by the Engineer. Submittal by the Contractor and review by the
Engineer shall be shown as separate activities.
5. Work to be performed by a subcontractor, agent, or any third party.
6. Allowances for delays that could result from normal inclement weather (time extensions due
to inclement weather will not be allowed).
7. Allowances for the time required by utilities (Owner’s and others) to locate, monitor, and
adjust their facilities as required.
The Engineer may request the Contractor to alter the progress schedule when deemed necessary in
the opinion of the Engineer, in the interest of public safety and welfare of the Owner, or for
coordination with any other activity of other contractors, the availability of all or portions of the job
site, or special provisions of this Contract, or to reasonably meet the completion date of the project.
The Contractor shall provide such revised schedule within 10 days of request.
If, at any time, in the opinion of the Engineer, the progress of construction falls significantly behind
schedule, the Contractor may be required to submit a plan for regaining progress and a revised
schedule indicating how the remaining Work items will be completed within the authorized contract
time.
The Contractor shall promptly report to the Engineer any conditions that the Contractor feels will
require revision of the schedule and shall promptly submit proposed revisions in the progress schedule
for acceptance by the Engineer. When such changes are accepted by the Engineer, the revised
schedule shall be followed by the Contractor.
Weekly Schedule. The Contractor shall submit a weekly progress schedule to the Engineer which sets
forth specific Work to be performed the following week, and a tentative schedule for the second week.
Failure to Maintain Progress Schedule. The Engineer will check actual progress of the Work against
the progress schedule a minimum of two times per month. Failure, without just cause, to maintain
progress in accordance with the approved schedule shall constitute a breach of Contract. If, through
no fault of the Contractor, the proposed construction schedule cannot be met, the Engineer will
require the Contractor to submit a revised schedule to the Engineer for acceptance. The approved
revisions will thereafter, in all respects, apply in lieu of the original schedule.
Failure of the Contractor to follow the progress schedule submitted and accepted, including revisions
09/11/2018
48
thereof, shall relieve the Owner of any and all responsibility for furnishing and making available all or
any portion of the job site, and will relieve the Owner of any responsibility for delays to the Contractor
in the performance of the Work.
The cost of preparing the progress schedule, any supplementary progress schedules, and weekly
schedules shall be considered incidental to the Contract and no other compensation shall be made.
1‐08.4 Notice to Proceed and Prosecution of the Work
Section 1‐08.4 is replaced with the following:
(******)
Notice to Proceed will be given after the Contract has been executed and the Contract bond and
evidence of insurances have been approved and filed by the Owner. The Contractor shall not
commence the Work until the Notice to Proceed has been given by the Engineer. The Contractor shall
commence construction activities on the project site within ten days of the Notice to Proceed date.
The Work thereafter shall be prosecuted diligently, vigorously, and without unauthorized interruption
until physical completion of the Work. There shall be no voluntary shutdowns or slowing of operations
by the Contractor without prior approval of the Engineer. Such approval shall not relieve the
Contractor from the contractual obligation to complete the Work within the prescribed Contract Time.
1‐08.5 Time For Completion
The first five paragraphs of Section 1‐08.5 are deleted and replaced with the following:
(******)
The Work shall be physically completed in its entirety within the time specified in the Contract
Documents or as extended by the Engineer. The Contract Time will be stated in “working days”, shall
begin on the Notice To Proceed date, or the date identified in the Notice to Proceed as “the first
working day”, and shall end on the Contract Completion date.
A non‐working day is defined as a Saturday, a Sunday, a day on which the Contract specifically suspends
Work, or one of these holidays: January 1, third Monday of January, Memorial Day, July 4, Labor Day,
November 11, Thanksgiving Day, the day after Thanksgiving, and Christmas Day. The day before
Christmas shall be a holiday when Christmas Day occurs on a Tuesday or Friday. The day after
Christmas shall be a holiday when Christmas Day occurs on a Monday, Wednesday, or Thursday. When
Christmas Day occurs on a Saturday, the two preceding working days shall be observed as holidays.
When Christmas day occurs on a Sunday, the two working days following shall be observed as holidays.
When holidays other than Christmas fall on a Saturday, the preceding Friday will be counted as a non‐
working day and when they fall on a Sunday the following Monday will be counted as a non‐working
day. The Contract Time has been established to allow for periods of normal inclement weather that,
from historical records, is to be expected during the Contract Time, and during which periods, Work is
anticipated to be performed. Each successive working day, beginning with the Notice to Proceed date
and ending with the Physical Completion date, shall be charged to the Contract Time as it occurs except
a day, or part of a day, which is designated a non‐working day or an Engineer determined unworkable
day.
The Engineer will furnish the Contractor a weekly report showing (1) the number of working days
charged against the Contract Time for the preceding week; (2) the Contract Time in working days; (3)
the number of working days remaining in the Contract Time; (4) the number of non‐working days; and
(5) any partial or whole days the Engineer declared unworkable the previous week. This weekly report
will be correlated with the Contractor’s current approved progress schedule. If the Contractor elects
to work 10 hours a day and 4 days a week (a 4‐10 schedule), and the fifth day of the week in which a
4‐10 shift is worked would ordinarily be charged as a working day, then the fifth day of that week will
be charged as a working day whether or not the Contractor works on that day.
The Contractor will be allowed 10 calendar days from the date of each report in which to file a written
protest of an alleged discrepancy in the Contract Time as reported. Otherwise, the report will be
deemed to have been accepted by the Contractor as correct.
The requirements for scheduling the Final Inspection and establishing the Substantial Completion,
Physical Completion, and Completion Dates are specified in Sections 1‐05.11 and 1‐05.12.
09/11/2018
49
Revise the seventh paragraph to read:
(******)
The Engineer will give the Contractor written notice of the completion date of the Contract after all
the Contractor’s obligations under the Contract have been performed by the Contractor. The
following events must occur before the Completion Date can be established:
1. The physical Work on the project must be complete; and
2. The Contractor must furnish all documentation required by the Contract and required by law, to
allow the Contracting Agency to process final acceptance of the Contract. The following
documents must be received by the Project Engineer prior to establishing a completion date:
a. Certified Payrolls (Federal‐aid Projects)
b. Material Acceptance Certification Documents
c. Annual Report of Amounts Paid as MBE/WBE Participants or Quarterly Report of Amounts
Credited as DBE Participation, as required by the Contract Provisions.
d. FHWA 47 (Federal‐aid Projects)
e. Final Contract Voucher Certification
f. Property owner releases per Section 1‐07.24
Section 1‐08.5 is supplemented as follows:
(******)
Within 10 calendar days after execution of the Contract by the Contracting Agency, the Contractor
shall provide the Contracting Agency with copies of purchase orders for all equipment items deemed
critical by the Contracting Agency, including but not limited to signal controller materials, lighting
standards, and signal standards required for the physical completion of the Contract. Such purchase
orders shall disclose the estimated delivery dates for the equipment.
All items of Work that can be performed without delivery of the critical items shall start and be
completed as soon as possible. At that time, the Engineer may suspend the Work upon request of the
Contractor until the critical items are delivered to the Contractor, if the Contracting Agency received a
purchase order within 10 calendar days after execution of the Contract by the Contracting Agency.
The Contractor will be entitled to only one such suspension of time during the performance of the
Work and during such suspension shall not perform any additional Work on the project. Upon delivery
of the critical items, contract time will resume and continue to be charged in accordance with Section
1‐08.
1‐08.6 Suspension of Work
Section 1‐08.6 is supplemented as follows:
(******)
Owner may at any time suspend the Work, or any part thereof, by giving notice to the Contractor in
writing. The Work shall be resumed by the Contractor within 14 calendar days after the date fixed in
the written notice from the Owner to the Contractor to do so.
The Contractor shall not suspend Work under the Contract without the written order of the Owner.
If it has been determined that the Contractor is entitled to an extension of time, the amount of such
extension shall be only to compensate for direct delays, and shall be based upon the Contractor's
diligently pursuing the Work at a rate not less than that which would have been necessary to complete
the original Contract Work on time.
1‐08.7 Maintenance During Suspension
Revise the second paragraph to read:
09/11/2018
50
(******)
At no expense to the Contracting Agency, the Contractor shall provide through the construction area
a safe, smooth, and unobstructed roadway, sidewalk, driveway, and path for public use during
suspension (as required in Section 1‐07.23 or the Special Provisions). This may include a temporary
road or detour.
1‐08.9 Liquidated Damages
Section 1‐08.9 is supplemented as follows:
(******)
In addition, the Contractor shall compensate the Owner for actual engineering inspection and
supervision costs and any other expenses and legal fees incurred by the Owner as a result of such
delay. Such labor costs will be billed to the Contractor at actual costs, including administrative
overhead costs.
In the event that the Owner is required to commence any lawsuit in order to enforce any provision of
this Contract or to seek redress for any breach thereof, the Owner shall be entitled to recover its costs,
including reasonable attorneys fees, from the Contractor.
1‐08.11 Contractor's Plant and Equipment
Section 1‐08.11 is a new Section:
(******)
The Contractor alone shall at all times be responsible for the adequacy, efficiency, and sufficiency of
his and his subcontractor's plant and equipment. The Owner shall have the right to make use of the
Contractor's plant and equipment in the performance of any Work on the site of the Work.
The use by the Owner of such plant and equipment shall be considered as extra Work and paid for
accordingly.
Neither the Owner nor the Engineer assumes any responsibility, at any time, for the security of the
site from the time the Contractor's operations have commenced until final acceptance of the Work by
the Engineer and the Owner. The Contractor shall employ such measures as additional fencing,
barricades, and watchmen service, as he deems necessary for the public safety and for the protection
of the site and his plant and equipment. The Owner will be provided keys for all fenced, secured areas.
1‐08.12 Attention to Work
Section 1‐08.12 is a new section:
(******)
The Contractor shall give his personal attention to and shall supervise the Work to the end that it shall
be prosecuted faithfully, and when he is not personally present on the Work site, he shall at all times
be represented by a competent superintendent who shall have full authority to execute the same, and
to supply materials, tools, and labor without delay, and who shall be the legal representative of the
Contractor. The Contractor shall be liable for the faithful observance of any instructions delivered to
him or to his authorized representative.
1‐09 MEASUREMENT AND PAYMENT
1‐09.1 Measurement of Quantities
Section 1‐09.1 is supplemented by adding the following:
(******)
Lump Sum. The percentage of lump sum Work completed, and payment will be based on the cost
percentage breakdown of the lump sum bid price(s) submitted at the preconstruction conference.
The Contractor shall submit a breakdown of costs for each lump sum bid item. The breakdown shall
list the items included in the lump sum together with a unit price of labor, materials, and equipment
for each item. The summation of the detailed unit prices for each item shall add up to the lump sum
bid. The unit price values may be used as a guideline for determining progress payments or deductions
09/11/2018
51
or additions in payment for ordered Work changes.
Cubic Yard Quantities. The Contractor shall provide truck trip tickets for progress payments only in
the following manner. Where items are specified to be paid by the cubic yard, the following tally
system shall be used.
All trucks to be employed on this Work will be measured to determine the volume of each truck. Each
truck shall be clearly numbered, to the satisfaction of the Engineer, and there shall be no duplication
of numbers.
Duplicate tally tickets shall be prepared to accompany each truckload of material delivered on the
project. All tickets received that do not contain the following information will not be processed for
payment:
1 Truck number
2 Quantity and type of material delivered in cubic yards
3 Drivers name, date and time of delivery
4 Location of delivery, by street and stationing on each street
5 Place for the Engineer to acknowledge receipt
6 Pay item number
7 Contract number and/or name
It will be the Contractor's responsibility to see that a ticket is given to the Engineer on the project for
each truckload of material delivered. Pay quantities will be prepared on the basis of said tally tickets.
Loads will be checked by the Engineer to verify quantity shown on ticket.
Quantities by Ton . It will be the Contractor's responsibility to see that a certified weight ticket is given
to the Inspector on the project at the time of delivery of materials for each truckload delivered. Pay
quantities will be prepared on the basis of said tally tickets, delivered to Inspector at time of delivery
of materials. Tickets not receipted by Inspector will not be honored for payment.
Each truck shall be clearly numbered to the satisfaction of the Engineer and there shall be no
duplication of numbers.
Duplicate tickets shall be prepared to accompany each truckload of material delivered to the project.
All tickets received that do not contain the following information will not be processed for payment:
1. Truck number
2. Truck tare weight (stamped at source)
3. Gross truckload weight in tons (stamped at source)
4. Net load weight (stamped at source)
5. Driver's name, date, and time of delivery
6. Location for delivery by street and stationing on each street
7. Place for the Engineer to acknowledge receipt
8. Pay item number
9. Contract number and/or name
1‐09.3 Scope of Payment
Section 1‐09.3 is supplemented by adding the following:
(******)
The bid items listed in Section 1‐09.14 will be the only items for which compensation will be made for
the Work described in each section of the Standard Specifications when the Contractor performs the
specified Work. Should a bid item be listed in a “Payment” clause but not in the Proposal Form, and
Work for that item is performed by the Contractor and the Work is not stated as included in or
incidental to a pay item in the Contract and is not Work that would be required to complete the intent
of the Contract per Section 1‐04.1, then payment for that Work will be made as for Extra Work
pursuant to a Change Order.
The words “Bid Item,” “Contract Item,” and “Pay Item,” and similar terms used throughout the
09/11/2018
52
Contract Documents are synonymous.
If the “payment” clause in the Specifications relating to any unit bid item price in the Proposal Form
requires that said unit bid item price cover and be considered compensation for certain Work or
material essential to the item, then the Work or material will not be measured or paid for under any
other unit bid item which may appear elsewhere in the Proposal Form or Specifications.
Pluralized unit bid items appearing in these Specifications are changed to singular form.
Payment for bid items listed or referenced in the “Payment” clause of any particular section of the
Specifications shall be considered as including all of the Work required, specified, or described in that
particular section. Payment items will generally be listed generically in the Specifications, and
specifically in the bid form. When items are to be “furnished” under one payment item and “installed”
under another payment item, such items shall be furnished FOB project site, or, if specified in the
Special Provisions, delivered to a designated site. Materials to be “furnished,” or “furnished and
installed” under these conditions, shall be the responsibility of the Contractor with regard to storage
until such items are incorporated into the Work or, if such items are not to be incorporated into the
Work, delivered to the applicable Contracting Agency storage site when provided for in the
Specifications. Payment for material “furnished,” but not yet incorporated into the Work, may be made
on monthly estimates to the extent allowed.
1‐09.6 Force Account
Section 1‐09.6 is supplemented as follows:
(******)
Owner has estimated and included in the proposal, dollar amounts for all items to be paid per force
account, only to provide a common proposal for Bidders. All such dollar amounts are to become a
part of the Contractor’s total bid. However, the Owner does not warrant expressly or by implication
that the actual amount of Work will correspond with those estimates. Payment will be made on the
basis of the amount of Work actually authorized by the Engineer.
1‐09.7 Mobilization
Section 1‐09.7 is supplemented as follows:
(******)
Mobilization shall also include, but not be limited to, the following items: the movement of
Contractor's personnel, equipment, supplies, and incidentals to the project site; the establishment of
an office, buildings, and other facilities necessary for Work on the project; providing sanitary facilities
for the Contractor's personnel; and obtaining permits or licenses required to complete the project not
furnished by the Owner.
This item shall also include providing the Engineer and the Inspectors with access to telephone,
facsimile machine, and copy machine during all hours the Contractor is working on the jobsite; and a
table and chair for their use when needed.
Payment will be made for the following bid item(s):
“Mobilization & Demobilization,” Lump Sum.
1‐09.9 Payments
Delete the third paragraph and replace it with the following:
(******)
Progress payments for completed Work and material on hand will be based upon progress estimates
prepared by the Engineer. A progress estimate cutoff date will be established at the preconstruction
meeting.
The initial progress estimate will be made not later than 30 days after the Contractor commences the
Work, and successive progress estimates will be made every month thereafter until the Completion
Date. Progress estimates made during progress of the Work are tentative, and made only for the
09/11/2018
53
purpose of determining progress payment. The progress estimates are subject to change at any time
prior to the calculation of the final payment.
The value of the progress estimate will be the sum of the following:
1. Unit Price Items in the Bid Form – the approximate quantity of acceptable units of Work
completed multiplied by the unit price.
2. Lump Sum Items in the Bid Form – the estimated percentage complete multiplied by the Bid Forms
amount for each lump sum item, or per the schedule of values for that item.
3. Materials on Hand – 100 percent of invoiced cost of material delivered to job site or other storage
area approved by the Engineer.
4. Change Orders – entitlement for approved extra cost or completed extra Work as determined by
the Engineer.
Progress payments will be made in accordance with the progress estimate less:
1. Retainage per Section 1‐09.9(1);
2. The amount of Progress Payments previously made; and
3. Funds withheld by the Contracting Agency for disbursement in accordance with the Contract
Documents.
Progress payments for Work performed shall not be evidence of acceptable performance or an
admission by the Contracting Agency that any Work has been satisfactorily completed.
Payments will be made by check or electronic transfer, issued by the Contracting Agency’s fiscal
officer, against the appropriate fund source for the project. Payments received on account of Work
performed by a subcontractor are subject to the provisions of RCW 39.04.250.
Section 1‐09.9 is supplemented as follows:
(******)
Applications for payment shall be itemized and supported to the extent required by the Engineer by
receipts or other vouchers showing payment for materials and labor, payments to subcontractors, and
other such evidence of the Contractor's right to payment as the Engineer may direct, including “red
line” as‐built drawings showing work installed by the contractor during the progress payment period.
The Contractor shall submit a progress report with each monthly request for a progress payment. The
progress report shall indicate the estimated percent complete for each activity listed on the progress
schedule (see Section 1‐08.3) and a revised and updated schedule to reflect the most current project
completion date.
1‐09.9(1) Retainage
Section 1‐09.9(1) is supplemented as follows:
(******)
The retained amount shall be released as stated in the Standard Specifications if no claims have been
filed against such funds as provided by law, and if the Owner has no unsatisfied claims against the
Contractor. In the event claims are filed, the Owner shall withhold, until such claims are satisfied, a
sum sufficient to satisfy all claims and to pay attorney's fees. In addition, the Owner shall withhold
such amount as is required to satisfy any claims by the Owner against the Contractor, until such claims
have been finally settled.
Neither the final payment nor any part of the retained percentage shall become due until the
Contractor, if requested, delivers to the Owner a complete release of all liens arising out of this
Contract, or receipts in full in lieu thereof, and, if required in either case, an affidavit that so far as the
09/11/2018
54
Contractor has knowledge or information, the release and receipts include all labor and materials for
which a lien could be filed: but the Contractor may, if any subcontractor refuses to furnish a release or
receipt in full, furnish a bond satisfactorily to the Engineer to indemnify the Owner against the lien. If
any lien remains unsatisfied after all payments are made, the Contractor shall reimburse to the Owner
all monies that the latter may be compelled to pay in discharging such lien, including all costs and
reasonable engineer's and attorney's fees.
1‐09.9(2) Contracting Agency’s Right to Withhold and Disburse Certain Amounts
Section 1‐09.9(2) is a new section:
(******)
In addition to monies retained pursuant to RCW 60.28 and subject to RCW 39.04.250, RCW 39.12 and
RCW 39.76, the Contractor authorizes the Engineer to withhold progress payments due or deduct an
amount from any payment or payments due the Contractor which, in the Engineer’s opinion, may be
necessary to cover the Contracting Agency’s costs for or to remedy the following situations:
1. Damage to another contractor when there is evidence thereof and a claim has been
filed.
2. Where the Contractor has not paid fees or charges to public authorities of
municipalities, which the Contractor is obligated to pay.
3. Utilizing material tested and inspected by the Engineer, for purposes not connected with
the Work (Section 1‐05.6).
4. Landscape damage assessments per Section 1‐07.16.
5. For overtime Work performed by City personnel per Section 1‐08.1(4).
6. Anticipated or actual failure of the Contractor to complete the Work on time:
a. Per Section 1‐08.9 Liquidated Damages; or
b. Lack of construction progress based upon the Engineer’s review of the Contractor’s
approved progress schedule, which indicates the Work will not be complete within
the contract time. When calculating an anticipated time overrun, the Engineer will
make allowances for weather delays, approved unavoidable delays, and suspensions
of the Work. The amount withheld under this subparagraph will be based upon the
liquidated damages amount per day set forth in Contract Documents multiplied by
the number of days the Contractor’s approved progress schedule, in the opinion of
the Engineer, indicates the Contract may exceed the Contract Time.
7. Failure of the Contractor to perform any of the Contractor’s other obligations under the
Contract, including but not limited to:
a. Failure of the Contractor to provide the Engineer with a field office when required by
the Contract Provisions.
b. Failure of the Contractor to protect survey stakes, markers, etc., or to provide
adequate survey Work as required by Section 1‐05.5.
c. Failure of the Contractor to correct defective or unauthorized Work (Section 1‐05.8).
d. Failure of the Contractor to furnish a Manufacture’s Certificate of Compliance in lieu
of material testing and inspection as required by Section 1‐06.3.
e. Failure to submit weekly payrolls, Intent to Pay Prevailing Wage forms, or correct
underpayment to employees of the Contractor or subcontractor of any tier as
required by Section 1‐07.9.
f. Failure of the Contractor to pay worker’s benefits (Title 50 and Title 51 RCW) as
required by Section 1‐07.10.
g. Failure of the Contractor to submit and obtain approval of a progress schedule per
Section 1‐08.3.
The Contractor authorizes the Engineer to act as agent for the Contractor disbursing such funds
as have been withheld pursuant to this Section to a party or parties who are entitled to
payment. Disbursement of such funds, if the Engineer elects to do so will be made only after
giving the Contractor 15 calendar days prior written notice of the Contracting Agency’s intent to
do so, and if prior to the expiration of the 15‐calendar day period,
1. No legal action has commenced to resolve the validity of the claims, and
2. The Contractor has not protested such disbursement.
09/11/2018
55
A proper accounting of all funds disbursed on behalf of the Contractor in accordance with this
Section will be made. A payment made pursuant to this section shall be considered as payment
made under the terms and conditions of the Contract. The Contracting Agency shall not be
liable to the Contractor for such payment made in good faith.
1‐09.9(3) Final Payment
Section 1‐09.9(2) is a new section:
(******)
Upon Acceptance of the Work by the Contracting Agency, the final amount to be paid the Contactor
will be calculated based upon a Final Progress Estimate made by the Engineer. Acceptance by the
Contractor of the final payment shall be and shall operate as a release:
1. To the Contracting Agency of all claims and all liabilities of the Contractor, other than claims
in stated amounts as may be specifically excepted in writing by the Contractor;
2. For all things done or furnished in connection with the Work;
3. For every act and neglect by the Contracting Agency; and
4. For all other claims and liability relating to or arising out of the Work.
A payment (monthly, final, retainage, or otherwise) shall not release the Contractor or the Contractor’s
Surety from any obligation required under the terms of the Contract Documents or the Contract Bond;
nor shall such payment constitute a waiver of the Contracting Agency’s ability to investigate and act
upon findings of non‐compliance with the WMBE requirements of the Contract; nor shall such
payment preclude the Contracting Agency from recovering damages, setting penalties, or obtaining
such other remedies as may be permitted by law.
Before the Work will be accepted by the Contracting Agency, the Contractor shall submit an affidavit,
on the form provided by the Engineer, of amounts paid to certified disadvantaged (DB), minority (MBE)
or women business enterprises (WBE) participating in the Work. Such affidavit shall certify the
amounts paid to the DB, MBE or WBE subcontractors regardless of tier.
On federally funded projects the Contractor may also be required to execute and furnish the
Contracting Agency an affidavit certifying that the Contractor has not extended any loans, gratuity or
gift and money pursuant to Section 1‐07.19 of these Specifications.
If the Contractor fails, refuses, or is unable to sign and return the Final Progress Estimate or any other
documents required for the final acceptance of the Contract, the Contracting Agency reserves the right
to establish a completion date and unilaterally accept the Contract. Unilateral acceptance will occur
only after the Contractor has been provided the opportunity, by written request from the Engineer, to
voluntarily submit such documents. If voluntary compliance is not achieved, formal notification of the
impending unilateral acceptance will be provided by certified letter from the Engineer to the
Contractor that will provide 30 calendar days for the Contractor to submit the necessary documents.
The 30‐calendar day deadline shall begin on the date of the postmark of the certified letter from
the Engineer requesting the necessary documents. This reservation by the Contracting Agency to
unilaterally accept the Contract will apply to contracts that are completed in accordance with Section
1‐08.5 for contracts that are terminated in accordance with Section 1‐08.10. Unilateral acceptance of
the Contract by the Contracting Agency does not in any way relieve the Contractor of the provisions
under contract or of the responsibility to comply with all laws, ordinances, and federal, state, and local
regulations that affect the Contract. The date the Contracting Agency unilaterally signs the Final
Progress Estimate constitutes the final acceptance date (Section 1‐05.12).
1‐09.11 Disputes and Claims
1‐09.11(2) Claims
Paragraph 5 is revised as follows:
(******)
Failure to submit with the Final Application for Payment such information and details as described in

less, submitted in accordance with Section 1‐09.11 and not resolved by nonbonding ADR processes,
shall be resolved through litigation, unless the parties mutually agree in writing to resolve the claim
through binding arbitration.
1‐09.13(3)A Administration of Arbitration
Revise the third paragraph to read:
(******)
The Contracting Agency and the Contractor mutually agree to be bound by the decision of the
arbitrator, and judgment upon the award rendered by the arbitrator may be entered in the Superior
Court of the county in which the Contracting Agency’s headquarters are located. The decision of the
arbitrator and the specific basis for the decision shall be in writing. The arbitrator shall use the
Contract as a basis for decisions.
1‐09.13(3)B Procedures to Pursue Arbitration
Section 1‐09.13(3)B is supplemented by adding:
(******)
The findings and decision of the board of arbitrators shall be final and binding on the parties, unless
the aggrieved party, within 10 days, challenges the findings and decision by serving and filing a petition
for review by the superior court of King County, Washington. The grounds for the petition for review
are limited to showing that the findings and decision:
1. Are not responsive to the questions submitted;
2. Is contrary to the terms of the contract or any component thereof;
3. Is arbitrary and/or is not based upon the applicable facts and the law controlling the issues
submitted to arbitration. The board of arbitrators shall support its decision by setting forth in writing
their findings and conclusions based on the evidence adduced at any such hearing.
The arbitration shall be conducted in accordance with the statutes of the State of Washington and
court decisions governing such procedure.
The costs of such arbitration shall be borne equally by the City and the Contractor unless it is the
board's majority opinion that the Contractor's filing of the protest or action is capricious or without
reasonable foundation. In the latter case, all costs shall be borne by the Contractor.

sets of results for evaluation.
2. Commercial Evaluation. If sampled and tested, HMA produced under Commercial Evaluation
and having all constituents falling within the tolerance limits of the job mix formula shall be
accepted at the unit contract price with no further evaluation. When one or more
constituents fall outside the commercial acceptance tolerance limits in Section 9‐03.8(7), the
lot shall be evaluated to determine the appropriate CPF. The commercial tolerance limits
will be used in the calculation of the CPF and the maximum CPF shall be 1.00. When less
than three sublots exist, backup samples of the existing sublots or samples from the street
shall be tested to provide a minimum of three sets of results for evaluation.
For each lot of HMA produced under Nonstatistical or Commercial Evaluation when the
calculated CPF is less than 1.00, a Nonconforming Mix factor (NCFM) will be determined. THE
NCFM equals the algebraic difference of CPF minus 1.00 multiplied by 60 percent. The Job
Mix Compliance Price Adjustment will be calculated as the product of the NCMF, the quantity
of HMA in the lot in tons, and the unit contract price per ton of the mix.
If a constituent is not measured in accordance with these Specifications, its individual pay factor will
be considered 1.00 in calculating the composite pay factor.

Section 7‐09.3(15) is revised to read as follows:
Long radius curves with radius of 400 feet or more, either horizontal or vertical, pipe may be laid
with standard pipe lengths by deflecting the joints. If the pipe is shown curved on the Plans and no
special fittings are shown, the Contractor can assume that the curves can be made by deflecting the
joints with standard lengths of pipe. If shorter lengths are required, the Plans will indicate maximum
lengths that can be used. The amount of deflection at each pipe joint when pipe is laid on a
horizontal or vertical curve shall not exceed 50% of the manufacturer’s printed recommended
deflections. The Contractor shall submit to the Engineer the pipe manufacturer's joint deflection
recommendations prior to pipe installation indicating deflections are within allowable AWWA

Where field conditions require deflection or curves not anticipated by the Plans, the Engineer will
determine the methods to be used. No additional payment will be made for laying pipe on curves as
shown on the Plans, or for field changes involving standard lengths of pipe deflected at the joints.
When special fittings not shown on the Plans are required to meet field conditions, additional
payment will be made for special fittings as provided in Section 1‐09.6.
When rubber gasketed pipe is laid on a curve, the pipe shall be jointed in a straight alignment and
then deflected to the curved alignment. Trenches shall be made wider on curves for this purpose.
Where pipe installation on curves requires the use of special fittings, concrete blocking shall be used
per Section 7‐09.3(21).
Where restrained joint pipe is installed on a curve, the Contractor shall submit the pipe manufacturer’s
recommendations to the Engineer for approval.

7‐09.3(23) Hydrostatic Pressure Test
Section 7‐09.3(23) is revised to read as follows:
Water main and appurtenances including service connections to the meter setter shall be tested in
sections of convenient length under a hydrostatic pressure equal to 150 psi in excess of that under
which they will operate or in no case shall the test pressure be less than 225 psi at the highest point
on the water main. Pumps, gauges, plugs, saddles, corporation stops, miscellaneous hose and piping,
and measuring equipment necessary for performing the test shall be furnished and operated by the
Contractor.
The Contractor shall obtain a hydrant meter permit from the City by completing a permit application
and making the required security deposits. The Contractor shall use the City’s issued hydrant meter
with an attached backflow prevention assembly to draw water from the City’ water system to fill the
water mains for poly‐pigging, testing, cleaning, disinfection and for subsequent flushing purposes.
There will be a charge for the water used for filling, testing, cleaning and disinfection of the water
mains.
Sections to be tested shall normally be limited to 1,500 feet or less. The Engineer may require that the
first section of pipe, not less than 1,000 feet in length, installed by each of the Contractor’s crews, be
tested in order to qualify the crew and the materials. Pipe laying shall not be continued more than an
additional 1,000 feet until the first section has been tested successfully.
The pipeline shall be backfilled sufficiently to prevent movement of the pipe under pressure. Thrust
blocks shall be in place and time allowed for the concrete to cure before testing. Where permanent
blocking is not required, the Contractor shall furnish and install temporary blocking and remove it after
testing.
Before applying the specified test pressure, the water main shall be slowly filled and air shall be
expelled completely from the pipe, valves and hydrants. If permanent air vents are not located at all
high points, the contractor shall install corporation cocks at such points so that the air can be expelled
as the line is filled with water. After all the air has been expelled, the corporation cocks shall be closed
and the test pressure applied. At the conclusion of the pressure test, the corporation cocks shall be
removed and plugged.
The Contractor shall perform a leakage test concurrently with the pressure test. The pressure test
shall be conducted for a 2‐hour period.
The test shall be accomplished by pumping the main up to the required pressure, stopping the pump
for 2 hours, and then pumping the main up to the test pressure again. During the test, the section
being tested shall be observed to detect any visible leakage.
A clean container shall be used for holding water for pumping up pressure on the main being tested.
This makeup water shall be sterilized by the addition of chlorine to a concentration of 50 mg/l.
The acceptability of the pressure test and leakage test will be determined by two factors as follows:
1. The loss in pressure shall not exceed 5 psi during the 2‐hour test period.
2. The quantity of water lost from the main and appurtenances shall not exceed the number of
gallons during the 2‐hour test period as listed in the following table.
09/11/2018

200 0.42 0.64 0.85 1.06 1.28 1.70 2.12 2.55
*If the pipeline under test contains sections of various diameters, the allowable leakage will be the
sum of the computed leakage for each size. For those diameters or pressures not listed, the formula
below shall be used:
The quantity of water lost from the main shall not exceed the number of gallons per hour as
determined by the formula:
L= SD√P__
266,400
where:
L = Allowable leakage in gallons/hour
S = Gross length of pipe tested, feet
D = Nominal diameter of the pipe in inches
P = Test pressure during the leakage test in psi
The quantity of water required to restore the pressure shall be accurately determined by either 1)
pumping from an open container of suitable size such that accurate volume measurements can be
made by the Engineer or, 2) by pumping through a positive displacement water meter with a sweep
unit hand registering one (1) gallon per revolution. The meter shall be approved by the Engineer.
Pressure gauges used in the test shall be accompanied with certifications of accuracy from a testing
Laboratory approved by the Engineer.
Any visible leakage detected shall be corrected by the Contractor regardless of the allowable leakage
specified above. Should the tested section fail to meet the pressure test successfully as specified, the
Contractor shall, at no additional expense to the Contracting Agency, locate and repair the defects and
then retest the pipeline.
All tests shall be made with the hydrant auxiliary gate valves open and pressure against the hydrant
inlet valve. After the test is completed, each valve shall be tested by closing each in turn and relieving
the pressure beyond. This test of the valve will be acceptable if there is no immediate loss of pressure
on the gauge when the pressure comes against the valve being checked. The Contractor shall verify
that the pressure differential across the valve does not exceed the rated working pressure of the valve.
Prior to calling out the Engineer to witness the pressure test, the Contractor shall have all equipment
set up completely ready for operation and shall have successfully performed the test to ensure that
the pipe is in satisfactory condition.
Defective materials or workmanship, discovered as a result of hydrostatic field test, shall be replaced
by the Contractor at no additional expense to the Contracting Agency. Whenever it is necessary to
replace defective material or correct the workmanship, the hydrostatic test shall be re‐run at the
Contractor’s expense until a satisfactory test is obtained.
7‐09.3(24)A Flushing and "Poly‐pigging"
Section 7‐09.3(24)A shall be revised and supplemented as follows:

coating on the rear of the "Poly‐pig" only. The "Poly‐pig" shall be cylinder shaped with bullet nose or
squared end. The “Poly‐pigs” shall be inserted in the pipes and retrieved form the pipes through
launching stations with vertical crosses and blow‐off assemblies as shown and on the Contract Plans
and Standard Plans.
If the main cannot be poly‐pigged, then a tap shall be provided large enough to develop a flow velocity
of at least 2.5 fps in the water main.
Taps required by the Contractor for temporary or permanent release of air, chlorination or flushing
purposes shall be provided by the Contractor as part of the construction of water mains.
The Contractor shall be responsible for disposal of treated water flushed from mains and shall
neutralize the wastewater for protection of aquatic life in the receiving water before disposal into any
natural drainage channel, i.e., receiving water, waters of the State, including wetlands. The Contractor
shall be responsible for disposing of disinfecting solution to the satisfaction of the Contracting Agency
and local authorities. At a minimum, chlorinated water shall be dechlorinated to a concentration of
0.1 parts per million (ppm) or less, and pH adjustment to within 6.5 – 8.5 standard units before
discharging to surface waters of the State or to a storm sewer system that drains to surface waters of
the State.
If approved by the Engineer and by the local authority responsible for the sanitary sewer system,
disposal of treated water from mains may be made to an available sanitary sewer, provided the rate
of disposal will not overload the sewer.

(******)
Treated water shall be retained in the pipe at least 16 hours but no longer than 48 hours. After the
retention period, the chlorine residual shall be tested at all pipe extremities and at other
representative points and shall measure at least 10 mg/L. If a measurement of less than 10 mg/L is
obtained repeat disinfection is required.
7‐09.3(24)N Final Flushing and Testing
Section 7‐09.3(24)N has been revised as follows:
(******)
Following chlorination, treated water shall be flushed from the newly‐laid pipe until the replacement
water throughout its length shows, upon test, the absence of chlorine. In the event chlorine is normally
used in the source of supply, then the tests shall show a residual not in excess of that carried in the
water supply system.
A sample tap shall be located ahead of the flushing hose for convenience and for sanitary sampling.
Before placing the lines into service, two satisfactory reports taken at least 15 minutes apart from each
sampling point shall be received from the local or State Health Department or from a State accredited
testing laboratory on samples collected from representative points in the new system. Samples will
be collected and bacteriological tests obtained by the Engineer.
At a minimum, chlorinated water shall be dechlorinated to a concentration of 0.1 parts per million
(ppm) or less, and pH adjustment to within 6.5 to 8.5 standard units, if necessary, before discharging
to surface waters of the State or to a storm sewer system that drains to surface waters of the State.

7‐21.3(1) Preparation
The Contractor shall make all necessary provisions to ensure service conditions and structural
conditions of host pipe are suitable for installation and warranty of the liner. The Contractor shall
verify the lengths in the field prior to ordering and prior to impregnation of the tube with resin, to
ensure that the tube will have sufficient length to extend the entire length of the run. The Contractor
shall also measure the inside diameter of the existing pipelines in the field prior to ordering liner so
that the liner can be installed in a tight‐fitted condition.
7‐21.3(1)A Flow Management
It shall be the Contractor's responsibility to maintain operation of the existing sewer systems
throughout the duration of the project without any interruption of sewer service. The Contractor
shall divert all flows around each segment of the pipe designated for rehabilitation. This diversion
shall consist of redirecting flow from an upstream manhole and discharging it to a manhole
downstream of the rehabilitation operation. This can be accomplished via a combination of pumping
and/or gravity flow. After the work is completed, flow shall be returned to the rehabilitated sewer
system. The area affected by the bypass operation shall be fully restored.
Bypass pumping shall be scheduled for continuous operation. Back‐up equipment shall be on‐site and
available for periods of maintenance, refueling or failure of the primary bypass pump(s) or diversion
system. Bypass pumping shall be done in such a manner as not to damage private or public property,
or create a nuisance or public menace. The bypass‐pumping pipe shall not block any driveways or
intersections unless approved by the Engineer. The sewage shall be pumped through a watertight
hose or pipe that is adequately protected from traffic. The discharge of raw sewage to private
property, city streets, sidewalks, storm sewer, or any location other than an approved sanitary sewer
is prohibited. The Contractor shall be liable for all cleanup, damages, and resultant fines should the
Contractor's operation cause any backups or overflows.
09/11/2018
115
The Contractor's bypass operation shall be sized to handle, at a minimum, the full pipe capacity in
each subject line removed from service. If flow conditions are greater than full pipe, the Contractor
may elect to wait for flow conditions to subside prior to removing the subject line from service.
Working days will not be charged for the period of time during which the flow is greater than full pipe.
No additional payment will be made for periods of high flows during which the Contractor elects to
wait for lower flows. Once the Contractor removes a section of line from service he/she is responsible
to bypass any and all flow in the system during construction, even in the event the system surcharges
and exceeds the full pipe capacity, until the line is returned to service.
All bypassing systems shall be approved by the Engineer. A plan for bypassing the existing sewer
system shall be submitted by the Contractor for review. The Contractor's plan for bypass pumping
shall be satisfactory to the Owner before the Contractor will be allowed to commence bypass
pumping. The sewage bypass pumping plan shall include an emergency response plan to be followed
in the event of a failure of the bypass pumping. The review of the bypassing system and equipment
by the Engineer shall in no way relieve the Contractor of his responsibility and public liability.
The Contractor shall coordinate activities with impacted property owners. Property Owners shall be
notified that their side sewer will be out of service for a specified period of time, as approved by the
Engineer.
When there exist situations where impacted properties cannot be disconnected, plugged, or
subjected to any other service interruption, i.e., hospitals, care facilities, restaurants, etc., bypass
pumping of the side sewer to the downstream sanitary sewer system shall be required prior to
insertion of the liner system. The Contractor shall verify whether a property is able to be interrupted
prior to lining operations. If the subject property’s side sewer requires bypass pumping, the costs for
the bypass pumping shall be covered by Force Account.

in the pipeline as follows:
1. Grout all defects as recommended by liner manufacturer or installer.
2. Grout all locations with active infiltration.
The determination of an excessive leak shall be made by the Owner’s representative and shall be
based on PACP leak designations. Leaks that would be categorized as a Runner(IR) – Severity 4 or
Gusher(IG) – Severity 5 shall be considered as excessive. Leaks categorized as Weeper(IW) – Severity
2 or Dripper(ID) – Severity 3 shall be considered incidental to the unit price for CIPP rehabilitation.
Make point repairs of any host pipe defect that can be removed by conventional sewer cleaning
equipment or by remotely performed repair methods acceptable to the Engineer.
Remove protruding laterals, rolled gaskets, roots, mineral deposits, and other objects
protruding into the host pipe, internally with a remote controlled cutter.
